Find the center of the trunk opening under the rear window and make a mark with a Sharpie or other such item you have handy. Find the center of the weatherstrip and make a similar mark. Line up the marks and start working your way around the trunk lip. I usually lay glue all across the top lip and around the top corners first. Work the weatherstrip carefully around the corners and have a bunch of spring type clothespins handy to hold things in place until the glue sets. Once I get the trunk strip glued across the top, around the corners, and clamped down with clothespins, I go have a cold one while the glue dries. Once this part is done and the glue is dry, the rest is just glue and work your way around to the end of the weatherstrip. If you have done everything right, the ends of the weatherstrip should come together in the center of the trunk latch. Hope this helps.
